-----------------------------------
Summary: slf4j binding conflict in slf4j-log4j12 and kafka-assembly
Key: KAFKA-1765
URL: https://issues.apache.org/jira/browse/KAFKA-1765
Project: Kafka
Issue Type: Bug
Components: log
Affects Versions: 0.8.0
Environment: slf4j-log4j12 kafka-assembly
Reporter: shizhu, wang
Assignee: Jay Kreps
Priority: Critical
Before our project use slf4j which binded to log4j for logging. But after
import
kafka-assembly.0.8.0.jar, log cannot work as expected. It just keep printing
log in console now instead of log files. Looked into kafka-assembly.0.8.0.jar
and find there is one SimpleLogger:
StringBuffer buf = new StringBuffer();
long millis = System.currentTimeMillis();
buf.append(millis - startTime);
buf.append(" [");
buf.append(Thread.currentThread().getName());
buf.append("] ");
buf.append(level);
buf.append(" ");
buf.append(name);
buf.append(" - ");
buf.append(message);
buf.append(LINE_SEPARATOR);
System.err.print(buf.toString());
if(t != null)
t.printStackTrace(System.err);
System.err.flush();
but I don't want this SimpleLogger in kafka-assembly. Can you advise how can I
get rid of this reference to this class(cannot remove the jar, because is
necessary)
